SYRINGE.

SPECIFICATION forming part of Letters Patent No. 559,620, dated May 5,1896.

Application filed May 16, 1895. Serial NO- 549,432. No model.)

To all whom it may concern:

Beit known that I, JOSEPH SHEARER, a citizen of the United States,residing at Loveland, in the county of Olerinont and State of Ohio, haveinvented certain new and useful Improvements in Vaginal Syringes; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, reference being had to the annexeddrawings, which form a part of this specification.

This invention relates to those vaginal syrin ges which are providedwith longitudinallyadjustable outflow-tubes, and my improvement includesa specific combination of devices for shifting such tubes so as toincrease or diminish the area of the instruments ventage, as hereinaftermore fully described.

In the annexed drawings, Figure 1 is a side elevation of my syringe.Fig. 2 is an axial section thereof. Fig. 3 is a side elevation of theoutflow-tube detached from the barrel. Fig. i is an enlargedendelevation of the head of the instrument, a pipe and tube of the samebeing sectioned and the adjusting devices arranged to permit thedetachment of a cap screwed to said head. Fig. 5 is a front elevation ofthe pad, the barrel and tube of the syringe being sectioned. Fig. 6 isan elevation of the inner side of the cap. Fig. 7 is a detail view.

The barrel of my syringe is a cylinder A, of any suitable size andmaterial and having its front end chainfered ed, as shown, andterminating with a bead or rounded swell a,

that facilitates the insertion of the instrn ment within a vagina. Therear end of the barrel is enlarged, so as to afford a head B, having afemale thread I), with which latter is engaged the male thread a of acap 0. In addition to this thread b the cap has a central circularorifice c and an inwardly-projecting annular neck 0', as more clearlyseen in Fig. (3. Projecting outwardly from this cap is a pipe D, towhich is attached a rubbcr hose (1, that conducts any desired wash orsolution into the syringe, the flow being either continuous orintermittent, as circumstances may suggest. Again, this cap has arearwardly projecting screw threaded stud E, that carries a disk nut F,whose periphery is notched at f, as more plainly seen in Fig. 4,

to enable a spring G to clear said nut when occasion requires. The freeend of said spring is notched at g to permit the nut F to normallyengage therewith, the opposite end of the spring being secured to theexterior of the outflow-tube H. This tube is usually of the taperingform shown, and has, near its smaller end, a compressible collar orpacking-ring I, that bears against the inner end of the neck a andprevents leakage at this joint of the instrument.

The front end of the tube has a flaring or bell mouth surrounded with ahead or swell h, the mouth being disposed at practically the same angleas the chamfered end a of the barrel. Furthermore, the front portion ofthis tube is somewhat less in diameter than the barrel, so as to affordan annular ventage J, the tube being centralized within said barrel by aset of small protuberances K, as more clearly seen in Fig. 5.

L is a tongue projecting from the tube and engaging with a guide I ofthe barrel, as represented in Fig. 7 the object of these devices L Zbeing to permit longitudinal shifting of said tube and yet prevent itturning in either direction. M is a hose attached to the rear end ofthis tube.

N is an elliptical plate made slightly concave in front and adapted tomove freely along the barrel A.

n is a soft pad or cushion attached to the front of plate N.

O is a coiled spring interposed between the plate N and head B.

Preparatory to using this instrument the patient is first laid upon herback, and the barrel A is then gradually inserted, the rounded swells ha, enabling this entrance to be effected without causing unnecessarypain. The syr inge is inserted its full length-say about four or fiveinches-at which time the soft pad '11 is in close contact with the mouthof the vagina and is held in this position by the action of the nowcompressed spring 0. The proper solution is next allowed to flow throughthe hose cl, pipe D, and barrel A and escape at the annular ventage J,so as to be brought into direct contact with the organ IOO requiringtreatment. Now while the solution is thus traversing the barrel theoutflow escapes through the tube II and hose M, the soft spring-pressedpad at preventing any material leakage at the mouth of the vagina.Consequently the patients garment-s will not be soiled by the foul ornoxious fluids washed out by the operation. 3y properly turning the nutF the tube II will be retracted and the area of ventage J reducedaccordingly, the result being a very fine lateral spraying of thesolution; but by manipulating said nut so as to advance said tube thesize of the outlet will be increased, and the discharge from the barrelwill then be more directly forward and in a heavier stream. A veryslight shifting of the tube II is all that is necessary to produce thesedifferent results; but this shift ing does not affect the packing-ringI, as its compressibility is sufficient to afford a perfectly tightjoint under all circumstances, and thereby prevent the two currents ofthe solution mingling together in the syringe.

To cleanse the instrument, it is necessary only to unscrew the cap O andthen turn the nut F until its notch f is in line with the spring G, asseen in Fig. 4, after which act said cap and its pipe D can be bodilydetached, thereby leaving the rear end of head 13 open and aliiordingready access to the interior of the syringe. Finally, the exact locationof pipe I) and nut F is immaterial; but they are usually diametricallyopposite eacn other, as seen in Fig. 4.

I claim as my invention 1. The combination, in a vaginal syringe. of thebarrel A a, screw-threaded head B 7). screwthreaded cap 0 e c c, pipe D,and longitudinally-movable tube II, which tube has a compressible collarI, that bears against the neck 0, of said cap, for the purposedescribed.

2. In avaginal syringe comprising abarrei A, and longitudinally-movableoutflow-tube II, the screw-threaded stud E, notched nut F f, and notchedspring G 9, arranged to operate as herein described.

In avaginal syringe comprising a barrel A, and longitudinally-inovableoutflow-tube H, the tongue L, and guide Z, for the purpose stated.

In testimony whereof I ahix my signature in presence of two witnesses.

JOSEPH SIIEARER.
